I receive several calls a week from this number, but when I tried to call back to determine who it is (I don't know anyone with this number) and have my number removed from what seems to be some sort of call list, there is a brief and weird pre-recorded voice that sounds like it says "die". The only action I can take at this time is to block the number.

Recieve calls from this number on my mobile phone.  They do not leave a message and they do not answer when I call back.  Voice message indicates dealer warranty has expired and I can press# to hear more or press 2 to be placed on do not call list.  I want them to stop calling me.

They call on cell number then hang up...can't call back...no answer

This number calls my bussiness phone late at night after hours  and does not leave a message.

Caller asked if I was the business owner. I asked him what business he was looking for. He asked again if I was the business owner. I asked again what business he was looking for. He hung up. I smiled.
